Filed: 1923-12-21
Abstract: 219,239. Fenchelle, H. E., and Lasarre (London), Ltd. Dec. 21, 1923. Filaments.-Filaments are made by first winding the wire cold and in open air into a flat coil on a reeling device, then setting the bends of the coil by electrically heating the wire-supporting members of the device in an inert gas, and finally heating the whole filament electrically and stretching it by moving the members of the device apart. A reeling device for carrying out the process consists of two pins 1, 2 slidably mounted in a slotted block 9 and secured therein by screws 7, 8. The ends of the pins rest in supports 16, 17 in a two-part bracket 18 at one end and in clamping screws 24, 25 in a similar bracket 19 at the other end. The two parts of each bracket are insulated from each other at 13 and the supports 17, 25 of the lower pin 2 are slidable in the brackets, by means of screws 26, 27 or the like, for stretching the filament. The whole device is mounted in a bell 14 having an inlet 15 for inert gas, and electrical supply is given at 28, 29, 30. The filament is wound in open air on the pins, some unwound distance being left between the slotted block 9 and the first coil to allow subsequent removal of the block. The pins are clamped against the supports 16, 17 by the screws 24, 25 and the block 9 is removed by loosening the screws 7, 8 and tilting the block obliquely across the unwound part of the pins. The bell is then placed in position and the pins are heated in an inert gas by closing the switches 28, 29. As soon as the pins begin to glow, the filament is heated, by closing the switch 30, and stretched, by lowering the pin 2. After formation, the block 9 is replaced and the pins and filament are removed from the apparatus.

Patent GB-325111-A (GB)
Abstract: 325,111. Heyne, W. O., Packman, P. J., and British Electric Pari- Mutuel, Ltd. Feb. 18, 1929. Selective signalling-apparatus.-The indications of an apparatus e.g. a totalizer, are transmitted over a plurality of line wires which are utilized in characteristic combinations to effect the operation of a distant indicator which is driven from an auxiliary source of power. As shown the totalling mechanism 2 - - 5, Fig. 1, which may be of the type described in Specification 287,767, [Class 106 (i), Calculating &c.], drives a disc 6 having a projection 8 adapted to operate ten pairs of switches, A,B; B,C; &c, in one revolution. The switches are connected in a manner characteristic of their position to different pairs of the line wires 10 - - 14, Fig. 3, connected to relays 15 - - 19 located at the distant indicator and having contacts connected to switches a - - e which co-operate with projections 9, Fig. 4, on a drum 7 rotatable with the indicator drum 1. Fig. 3 shows a developed diagram of the totalizer and indicator switching arrangements. In the position of the apparatus shown in Figs. 1 and 4, switches A, B are closed to energize relays 15, 16 but contacts a, b are opened by the projections 9 on the drum 7 corresponding to the indicated position of the totalizer, to open the circuit of the electromagnet 20 of the clutch mechanism 24, 25 and thereby maintain the indicator drum 1 at rest. If now the disc 6 rotates, the electromagnet 20 is energized by operation of relays 17 &c. over closed contacts c &c. and the latch 29 is raised to allow engagement of the clutch member 25 with the member 24 which is driven by the continuously rotating shaft 21. The indicating drum 1 is thus driven to follow the rotation of the disc 6 until when the latter stops in the new position, the circuit of the electromagnet 20 is opened at a pair of contacts in the group a - - e by the projections 9 corresponding to a similar position of the indicator drum. Instead of utilizing pairs of line wires to effect selection, any suitable, combination may be employed e.g. the wires may be employed in twos or partly in fours and partly in twos. The Provisional Specification also refers to Specifications 324,906; and 324,907, [Class 106 (i), Calculating &c.].
